Abstract
The present invention relates to the modification of lignin biosynthesis in plants and, more particularly, to enzymes involved in the lignin biosynthetic pathway and nucleic acids encoding such enzymes.
Claims17
A substantially purified or isolated nucleic acid or nucleic acid fragment encoding cinnamoyl-CoA reductase (CCR) or cinnamyl alcohol dehydrogenase (CAD) from a Lolium species.
A substantially purified or isolated nucleic acid or nucleic acid fragment selected from the group consisting of:
- (a) a nucleic or nucleic acid fragment encoding CCR comprising the sequence shown in Sequence ID No:
- 7;
- (b) a nucleic acid or nucleic acid fragment encoding CAD comprising a nucleotide sequence selected from the group consisting of the sequences shown in Sequence ID Nos:
- 9, 11, 14 and 16;
- (c) the complements of the sequences recited in (a) and (b);
- (d) sequences antisense to the sequences recited in (a), (b) and (c);
- and (e) functionally active fragments and variants of the sequences recited in (a), (b), (c) and (d).
A substantially purified or isolated CCR or CAD polypeptide from a Lolium species.
A substantially purified or isolated polypeptide selected from the group consisting of:
- (a) a CCR polypeptide comprising an amino acid sequence shown in Sequence ID No:
- 8;
- (b) a CAD polypeptide comprising an amino acid sequence selected from the group consisting of the sequence shown in Sequence ID Nos:
- 10, 12 and 15;
- and
- (c) functionally active fragments and variants of the sequences recited in (a) and (b).
